What is the best imaging modality to evaluate a suspected meniscal tear, and what adjunct imaging helps assess bone changes?

• A. MRI is best; X-ray to assess for fracture or OA as an adjunct.
• B. X-ray is best; MRI is rarely used.
• C. Ultrasound is best for soft tissue assessment.
• D. CT is best for evaluating meniscal tears.

Answer: (A)

The main idea is that evaluating a suspected meniscal tear hinges on the best soft-tissue detail available. MRI provides high-contrast, multiplanar images of the knee’s internal structures, allowing direct visualization of the menisci and any tears, degenerative changes, or associated injuries like ligament sprains. This makes it the most sensitive and specific tool for diagnosing meniscal pathology.

For bone problems that might accompany a knee issue—such as fractures or osteoarthritis—plain X-ray is the most practical adjunct. It quickly shows bone integrity, joint alignment, and degenerative changes (bone spurs, joint space narrowing) that can influence treatment decisions. While CT and ultrasound have roles in other scenarios, they don’t match MRI for soft-tissue detail or X-ray for broad bone assessment.

So, MRI is used to evaluate the meniscus, with X-ray as the go-to adjunct to assess bone changes.
